Abstract

The invention discloses a culture method for promoting growth of marine product shellfish. In the culture process, shellfish is at least divided into large and small specifications according to the shell size based on the cultured shellfish size at certain stage, and different specifications of shellfish are separately cultured. According to the invention, the shellfish is divided into large and small specifications according to the shell size and separately cultured, the phenomenon that the small individual growth is limited because larger individuals are high in physiologic metabolism level, large in ingestion amount and compete food with the small individuals is avoided, larger individuals and small individuals are separately cultured, and the competition is reduced and the small individuals can obtain enough food, thus the growth rate is obviously increased, the culture time is greatly shortened and the culture cost is saved. As compared with shellfish which is not cultured separately, the individual size and growth rate of the shellfish are wholly increased.

Description

A kind of cultural method that promotes the marine shellfish growth
Technical field:
The invention belongs to aquaculture field, be specifically related to a kind of cultural method that promotes the marine shellfish growth.
Background technology:
Pteria martensii (Pinctada martensi), Chlamys nobilis (Chlamys nobilis) are distributed widely in the torrid zone, sea areas, subtropics such as the Guangdong, Guangxi, Sound Velocity in Southern Taiwan Strait of China.Be the important component part of ocean food web, also can filter the food algae, have important ecological significance.They are one of main mariculture shellfishes in China south, and pteria martensii is the important kind of cultivating sea water pearls, and Chlamys nobilis is a kind of fast edible economic shellfish of growth that has, and all has higher economic value.But owing to constantly enlarged by the breed scale, cultural method is single, and the influence of factor such as the shallow-sea ecology environment is unbalance, the breed intermediate frequency of marine shellfish the phenomenons such as existing poor growth, individuality is little, individual difference is big that occur frequently.
Summary of the invention:
The purpose of this invention is to provide a kind of growth rate and culture-cycle big or small, that can shorten the commodity shellfish effectively that can improve pteria martensii and Chlamys nobilis, reduce the cultural method of the promotion marine shellfish growth of aquaculture cost.
The present invention finds that through experiment for pteria martensii and Chlamys nobilis, in same cultured population, the physiological metabolism level of more large-scale individuality is high, food ration is big; Meeting and small individual generation flood competition, thereby the growth of restriction small individual are as separately culturing them; To reduce this competition, and make small individual obtain sufficient food, thereby promote its growth; To shorten the culture-cycle, reduce aquaculture cost, thereby realized the object of the invention.
The cultural method of promotion marine shellfish of the present invention growth is characterized in that, may further comprise the steps:
In forming process, according to the size of certain stage breeding shellfish, it is divided into large and small two kinds of specifications at least by the big young pathbreaker of shell, and the shellfish of different size is cultured respectively.
Described shellfish is preferably pteria martensii (Pinctada martensi); Further preferred; Described pteria martensii is the pteria martensii in 1 length of time; High 50mm is a standard by shell, is divided into above individuality of the high 50mm of shell and the individuality below the high 50mm of shell, and the individuality of two kinds of different sizes is separately cultured.
Described shellfish is preferably Chlamys nobilis (Chlamys nobilis); Further preferred; Described Chlamys nobilis be 1 the length of time Chlamys nobilis; High 55mm is a standard by shell, is divided into above individuality of the high 55mm of shell and the individuality below the high 55mm of shell, and the individuality of two kinds of different sizes is separately cultured.
Compared with prior art, beneficial effect of the present invention is following:
Shellfish is divided into big or small two kinds of specifications at least by the shell size separately cultures, can avoid like this because the physiological metabolism level of more large-scale individuality is high, food ration is big, meeting and small individual generation flood competition; Thereby the growth of restriction small individual is separately cultured them, just can reduce this competition; Make small individual obtain sufficient food; Growth rate obviously improves, and has shortened culturing time greatly, has practiced thrift aquaculture cost.Compare with being regardless of the specification breed, on the whole individual size and growth rate are improved.
Embodiment:
Following examples are to further specify of the present invention, rather than limitation of the present invention.
Embodiment 1:
2011.5 month the pteria martensii in 1 age is divided into two kinds of specifications by the high size of shell; A kind of is as one group (group 1) with the individuality more than the high 50mm of shell; A kind of is as another group (group 2) with the shellfish below the high 50mm of shell; Shellfish with the unsizing specification compares (group 3), and it is foster that 5 layers of cage tool hangs as the breed instrument, every layer of 40 shellfish.When culturing beginning, shell height of group 1, length and width, body weight are all greater than organizing 2 and organize 3; Group 3 is greater than group 2.After culturing in 3 months, its big or small proterties is specifically as shown in table 1, and 4 proterties of group 1 organize 2 also greater than group 3 simultaneously still greater than group 2, group 3.Explain thus shellfish separately cultured by specification after, the shellfish of small-sized specification has growth faster, even has surpassed the size of control group, and large-scale individuality still keeps its large-scale advantage.
Show the big or small proterties of 1:3 group when culturing beginning and finishing
Embodiment 2:
2011.5 month the Chlamys nobilis in 1 age is divided into (group 1) and following two groups (group 2) more than the 55mm by the shell height, compares (organizing 3) with the shellfish of unsizing specification, equal densities breed 3 months.Concrete outcome is shown in table 2 and table 3, and when culturing beginning, 4 proterties of group 1 are greater than group 2,3, and group 2 is less than group 3.After experiment finished, height, length and width and 4 proterties of body weight of group 1 were still greater than group 2,3, and group 2 is dwindled with the difference in size of 3 of groups, also promptly organized 2 relative growth rate greater than organizing 3.Simultaneously, the average growth rate of group 1,2 is explained thus the shellfish of different size is separately cultured the growth that can promote small-sized shellfish greater than group 3, helps the middle-size and small-size individuality of cultured population and reach commercial specification fast.
Show the big or small proterties of 2:3 group when culturing beginning and finishing
Show the relative growth rate of 3:3 group scallop in 3 months culture-cycle
Group High Long Wide Body weight
1 28.52% 32.79% 37.06% 129.45%
2 63.53% 70.59% 78.7% 343.09%
3 43.2% 48% 52.36% 191.13%
